Hello, I'm Donner60. I noticed that you made a change to an article, The North Wall, but you didn't provide a source. I’ve removed it for now, but if you’d like to include a citation to a reliable source and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. Donner60 (talk) 03:25, 10 November 2019 (UTC)

 * Please see:


 * No original research. "Wikipedia articles must not contain original research. The phrase "original research" (OR) is used on Wikipedia to refer to material—such as facts, allegations, and ideas—for which no reliable, published sources exist. This includes any analysis or synthesis of published material that serves to reach or imply a conclusion not stated by the sources. To demonstrate that you are not adding OR, you must be able to cite reliable, published sources that are directly related to the topic of the article, and directly support the material being presented...."


 * No original research. "Main page: Verifiability. Wikipedia's content is determined by previously published information rather than by the personal beliefs or experiences of its editors. Even if you're sure something is true, it must be verifiable before you can add it. The policy says that all material challenged or likely to be challenged, and all quotations, needs a reliable source; what counts as a reliable source is described at Verifiability."


 * Verifiability. "Base articles on reliable, third-party, published sources with a reputation for fact-checking and accuracy. Source material must have been published, the definition of which for our purposes is "made available to the public in some form". Unpublished materials are not considered reliable."


 * Verifiability. "All content must be verifiable. The burden to demonstrate verifiability lies with the editor who adds or restores material, and is satisfied by providing an inline citation to a reliable source that directly supports the contribution."


 * Verifiability, not truth. Essay. "Wikipedia editors are not indifferent to truth, but as a collaborative project, its editors are not making judgments as to what is true and what is false, but what can be verified in a reliable source and otherwise belongs in Wikipedia."


 * Verifiability. "In Wikipedia, verifiability means that other people using the encyclopedia can check that the information comes from a reliable source. Wikipedia does not publish original research. Its content is determined by previously published information rather than the beliefs or experiences of its editors. Even if you're sure something is true, it must be verifiable before you can add it. When reliable sources disagree, maintain a neutral point of view and present what the various sources say, giving each side its due weight."
